Description

CBTC-based interval remote door opening control method, system, device and storage medium Technical Field

[0001] The present invention relates to the field of train signal control, and in particular to a CBTC-based interval remote door opening control method, system, device and storage medium. Background Art

[0002] Currently, the commonly used signaling system in urban rail transit is the CBTC (Cellular Train Control) system based on vehicle-to-ground wireless communication. With the development of technology and the improvement of the automation level of signaling systems, more and more cities have adopted the GOA4 level fully automatic unmanned subway CBTC system.

[0003] In the case of an unmanned GOA4 Level CBTC system, which lacks a driver, forced evacuation of passengers during a train stop typically requires passengers to manually unlock the doors by activating the emergency handle under the remote guidance of a central operator. Furthermore, since passengers rarely use the emergency handle and are unfamiliar with its operation, sudden evacuations can cause significant stress. Consequently, the time it takes for passengers to open the doors and evacuate the train on their own is considerable, posing a risk in emergencies requiring a short period of time to disembark.

[0004] Furthermore, in traditional manned GOA2 and GOA3 subway CBTC systems, since they employ a driver, when a train makes an emergency stop and passengers need to evacuate, the driver and central operator can manually open the doors and guide passengers out after confirming that evacuation conditions are safe. However, if the driver becomes incapacitated, such as due to a sudden illness, and a passenger evacuation situation occurs, passengers are left waiting inside the train for assistance, such as from other drivers approaching the train.

[0005] A search revealed Chinese invention patent application CN116714642A, which discloses a train-interval evacuation protection method. This method responds to an evacuation request from a train and, based on the train's location and direction of travel, establishes an evacuation protection zone for the train. This zone then provides evacuation protection for other trains associated with it. This technology only describes the process for setting the evacuation protection zone and does not address remote door opening control.

[0006] Therefore, it is necessary to consider the interval remote door opening control method in the above scenario.

[0007] Summary of the Invention

[0008] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a CBTC-based interval remote door opening control method, system, equipment and storage medium, which can effectively and safely remotely and actively control the interval door opening.

[0009] The purpose of the present invention can be achieved by the following technical solutions:

[0010] According to a first aspect of the present invention, a method for remote door opening control based on CBTC is provided, the method comprising:

[0011] In the CBTC train control system based on train-to-ground wireless communication, the central operator interacts with the automatic train monitoring subsystem (ATS) through the human-machine interface (HMI). The ATS receives instructions from the central operator and issues remote section door opening instructions to selected trains.

[0012] After receiving the remote section door opening command, the onboard controller performs door opening control based on the current train status information, including:

[0013] If the train has come to a complete stop and is currently located within the evacuation platform, the onboard controller authorizes the opening of the door on the evacuation platform side. The central operator receives feedback on the successful remote door opening via the human-machine interface (HMI) and remotely guides passengers to enter the evacuation platform through the opened door; and

[0014] If the train has not stopped, or if the train has stopped but is not currently at the evacuation platform, it is determined that the train does not have the conditions for remote door opening and the doors are opened manually for passenger evacuation.

[0015] As an optimal technical solution, the onboard controller authorizes opening the door on the evacuation platform side. Specifically, after the onboard controller successfully receives the remote section door opening command, it sends a section door opening enable to the train to open the door on the evacuation platform side.

[0016] As an optimal technical solution, the remote interval door opening instruction is issued using a secondary confirmation method.

[0017] As a preferred technical solution, the train status information obtained by the intermediate operator from the human-machine interface HMI includes positioning information, stop information and door status information.

[0018] As a preferred technical solution, the on-board controller determines whether the train has stopped steadily based on the train's zero speed information.

[0019] As a preferred technical solution, the evacuation platform is pre-stored in an electronic map built into the vehicle-mounted controller.

[0020] As a preferred technical solution, the process of determining whether the train is currently located within the evacuation platform is as follows: the onboard controller determines whether the entire train is within the evacuation platform based on its own positioning information and the mileage range of the evacuation platform in the built-in electronic map.

[0021] As a preferred technical solution, the remote section door opening command is transmitted through the interface between the automatic train monitoring subsystem ATS and the on-board controller.

[0022] As an optimal technical solution, within an effective communication cycle between the train automatic monitoring subsystem ATS and the on-board controller, if the train receives a remote door opening command, remote door opening control will be performed; otherwise, the train will be treated as not meeting the conditions for remote door opening.

[0023] As a preferred technical solution, the remote guidance of passengers to enter the evacuation platform through the open doors includes train broadcasting, train passenger information subsystem PIS and train emergency intercom.

[0024] As a preferred technical solution, if the train has not stopped, or if the train has stopped but is not currently located at the evacuation platform, it is determined that the train does not meet the conditions for remote door opening, and the doors are opened manually to evacuate passengers, specifically as follows:

[0025] The remote door opening failure information is fed back to the central operator through the human-machine interface (HMI). After the central operator learns of it, he uses the train broadcast to inform the passengers and remotely instructs the passengers to turn the emergency handle to the unlock position and manually open the train door for evacuation.

[0026] As a preferred technical solution, the train control system CBTC based on vehicle-to-ground wireless communication is in normal operation.

[0027] As a preferred technical solution, the method is applicable to GOA2, GOA3, and GOA4 subway train control systems CBTC based on vehicle-to-ground wireless communication.

[0028] According to a second aspect of the present invention, a system using the CBTC-based section remote door opening control method is provided. The system relies on a train control system (CBTC) based on vehicle-to-ground wireless communication and specifically includes:

[0029] The remote section door opening command issuing module is used for the central operator to interact with the automatic train monitoring subsystem (ATS) through the human-machine interface (HMI). The automatic train monitoring subsystem (ATS) receives the central operator's command and issues the remote section door opening command to the selected train; and

[0030] The section remote door opening control module is used to control the doors according to the current train status information after the onboard controller receives the remote section door opening command, including:

[0031] If the train has come to a complete stop and is currently located within the evacuation platform, the onboard controller authorizes the opening of the door on the evacuation platform side. The central operator receives feedback on the successful remote door opening via the human-machine interface (HMI) and remotely guides passengers to enter the evacuation platform through the opened door; and

[0032] If the train has not stopped, or the train has stopped but is not currently at the evacuation platform, it is determined that the train does not meet the conditions for remote door opening and the information is fed back to the central operator through the human-machine interface (HMI). After the central operator learns of the remote door opening failure, he or she remotely instructs passengers to manually open the train doors for evacuation.

[0033] According to a third aspect of the present invention, an electronic device is provided, comprising a memory and a processor, wherein a computer program is stored in the memory, and the processor implements the method when executing the program.

[0034] According to a fourth aspect of the present invention, a computer-readable storage medium is provided, on which a computer program is stored, and when the program is executed by a processor, the method described above is implemented.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1) After receiving instructions from the central operator through the CBTC system, the present invention issues a remote section door opening instruction, remotely and actively opens the section train doors, realizing effective remote door opening control and section evacuation.

[0037] 2) During the train door opening process, the door opening enable is given and supervised by the CBTC system, which provides higher safety.

[0038] 3) Controlled by central operators, the entire evacuation process is more in line with pre-established emergency plans than passengers activating the passenger emergency handle to unlock the doors and manually opening the doors to evacuate. The central operator is fully responsible for the operation of the equipment throughout the evacuation process, improving the overall efficiency of the interval evacuation and making it more orderly and safer.

[0039] 4) In a manned CBTC system, the driver can open the door for evacuation. The evacuation is centrally managed by a central operator, reducing the driver's workload.

[0040] 5) The present invention does not require additional hardware. It only requires adding interface information for remote door opening to the interface of the existing ATS-vehicle controller. This can be achieved after data configuration, and is simple to implement.

[0041] 6) The interval remote door opening control of the present invention is based on the CBTC system, and is applicable to GAO2 and GAO3 manned CBTC systems, and is also applicable to GAO4 unmanned CBTC systems, with a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 2 shows an implementation example and data flow diagram. DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0045] Example

[0046] This embodiment provides a method for remote door opening control within a certain interval based on CBTC, which includes:

[0047] In the CBTC train control system based on train-to-ground wireless communication, the central operator interacts with the automatic train monitoring subsystem (ATS) through the human-machine interface (HMI). The ATS receives instructions from the central operator and issues remote section door opening instructions to selected trains; and

[0048] After receiving the remote section door opening command, the train onboard controller performs door opening control according to the current train status information, including:

[0049] If the train has come to a complete stop and is currently located within the evacuation platform, the onboard controller authorizes the opening of the door on the evacuation platform side. The central operator receives feedback on the successful remote door opening via the human-machine interface (HMI) and remotely guides passengers to enter the evacuation platform through the opened door; and

[0050] If the train has not stopped, or if the train has stopped but is not currently at the evacuation platform, it is determined that the train does not have the conditions for remote door opening and the doors are opened manually for passenger evacuation.

[0051] Next, the method of this embodiment will be described in detail with reference to Figures 1 and 2 .

[0052] S1: The ATS subsystem receives instructions from the central operator on the ATS human-machine interface (HMI) based on train information, such as train number, and issues remote door opening instructions to the selected train;

[0053] S2: Within an effective communication cycle between the ATS and the onboard controller, if the train receives a remote door opening command, it enters S3; otherwise, it enters S8;

[0054] S3: The onboard controller determines whether the train has stopped steadily by checking whether the train is at zero speed. If the train has stopped steadily, the controller proceeds to S4; otherwise, the controller proceeds to S8.

[0055] S4: The onboard controller determines whether the train is within the evacuation platform by comparing its own positioning with the evacuation platform mileage range in the electronic map. If so, the process proceeds to S5; otherwise, the process proceeds to S8.

[0056] S5: The onboard controller enables the train door opening and opens the door on the side with the evacuation platform according to the electronic map.

[0057] S6: The onboard controller sends the door opening success alarm to the ATS HMI, and the center operator organizes passenger evacuation according to the operating procedures;

[0058] S7: The central operator remotely organizes passengers to get off the train and evacuate, such as through train broadcasts, train PIS and train emergency intercoms;

[0059] S8: The train does not meet the remote door opening conditions and the door opening fails;

[0060] S9: The onboard controller sends the door opening failure alarm to the ATS HMI;

[0061] S10: The center operator organizes passenger evacuation through other means, such as using train broadcasting to inform passengers: turn the passenger emergency handle to the unlock position and manually open the door.

[0062] The above is an introduction to the method embodiment. The following system embodiment, a CBTC-based interval remote door opening control system, will further illustrate the solution of the present invention.

[0063] The system relies on the CBTC train control system based on vehicle-to-ground wireless communication, which specifically includes:

[0064] The remote section door opening command issuing module is used for the central operator to interact with the automatic train monitoring subsystem (ATS) through the human-machine interface (HMI). The automatic train monitoring subsystem (ATS) receives the central operator's command and issues the remote section door opening command to the selected train; and

[0065] The section remote door opening control module is used to control the doors according to the current train status information after the onboard controller receives the remote section door opening command, including:

[0066] If the train has come to a complete stop and is currently located within the evacuation platform, the onboard controller authorizes the opening of the door on the evacuation platform side. The central operator receives feedback on the successful remote door opening via the human-machine interface (HMI) and remotely guides passengers to enter the evacuation platform through the opened door; and

[0067] If the train has not stopped, or the train has stopped but is not currently at the evacuation platform, it is determined that the train does not meet the conditions for remote door opening and the information is fed back to the central operator through the human-machine interface (HMI). After the central operator learns of the remote door opening failure, he or she remotely instructs passengers to manually open the train doors for evacuation.

[0068] The system data flow shown in Figure 2 specifically includes:

[0069] The central operator interacts with the ATS system through the human-machine interface (HMI). The remote door opening command issued by the ATS subsystem to the vehicle is issued using a secondary confirmation method to avoid operator misoperation of the interface. In addition, the ATS subsystem will also feed back the execution results to the HMI for the operator to view, forming a closed-loop feedback loop on the execution results of the command.

[0070] The ATS subsystem feeds back train information, including train location and train door status, to the HMI. The vehicle-to-ground wireless communication between the ATS and the onboard controller reuses the existing channel. It only needs to add the "door opening command issuance" code bit to the existing CBTC ATS-onboard controller vehicle-to-ground wireless channel and interface protocol. The train door status is already included in the original CBTC vehicle-to-ground wireless transmission information. After the onboard controller successfully receives the door opening command, it issues a door opening enable for a section to the vehicle (usually the train only has the door opening enable when it stops precisely at the platform), and opens the door on the corresponding evacuation platform side. The central operator notifies the passengers and organizes the passenger evacuation in an orderly manner according to the operational evacuation plan and procedures.
